Poly Subframe bushings Vs. Aluminum

How bad is it to use Aluminum subframe bushing replacements on a daily driving s14 Vs. Polyutherane ones? I ask because I am bringing down my subframe to replace my busted fuel tank so I want to take advantage of this opportunity to replace the subframe bushings. Some aluminums just seem easier to install since you dont have to deal with ripping the worn out ones from the frame. I hear the aluminums, since they stiffen, will help with drifting but how bad are day for daily driving? I have also heard they make lots of noise. Is all this true? Please advice.

they are going to make things a lil more noisy back there and you still have to get all of the old bushing remains out... so... no lol as far as daily driving.. not a clue
 
Solid bushings are proven to give you wood at first then later they give you hemorrhoids then you can be a part of the bleeding anus crew
 
i installed peak performance subframe spacers and they are ok but they squeak like a sob, and still dont hold the subframe that tight i would reccomend aluminum collars instead easy install and cheap.

Why dont the spacers hold the subframe tight to the chassis? Did you support the subframe with a jack while you torqued the nuts with oil in a criss cross pattern? Are the nuts bottoming out on the shank of the stud coming down from the body?

I replaced my subframe bushings with energy suspension polyurethane z32 bushings, you have to cut a little bit off the height to make them fit correctly but its not a big deal, a razor blade will do it, no issues.

Ive never driven or ridden in a car with solid subframe bushings.

You have to take out the old bushing and its metal sleeve to install aluminum and polyurethane bushings. Aluminum Collars I believe are installed with the original bushing in place.
 
If you want a quiet ride, don't get aluminum subframe bushings. You'll hear your diff loud and clear. Plus ever other bit or road noise will transmit straight through to the cabin.

Energy already makes them for 240sx. Why modify 300zx bushings? Just wondering.

As far as easy-to-install, I was talking about the collars. Sorry for the lack of detail :eek:

I'm installing solid aluminum subframe bushings on my daily s14 this week.

I'll let you know how it goes
 
I've run solid aluminum ones from ls automotive for years now. They work great and after a while you don't notice the extra noise. Worth the trade off imo...
 
i just got some aluminum ones haven't driven on them yet but i bet its gonna help alot with body roll. :bigthumbu
 
don't waist your time and money with collars; cut, burn and/or scape the factory rubber out and replace. Aluminium here.

i'm in the exact same situation as you.

i can't believe nissan makes us remove the driveshaft and subframe just to remove the tank. especially since (in every other instance), nissan has made working on the s14 easy.


anyway, i found some SPL aluminum subframe bushings..

anybody have any experience?


i also hear aluminum bushings are hard to install..
